If you haven't seen us advertise this before, dyno day (okay, this event is a dyno NIGHT) offers the chance to get a baseline or updated dyno numbers on your car for a smaller fee than on normal workdays. Cost is $75 for a slot, $25 additional for air/fuel analysis. (Normal price is $100 and $35 for a/f.) Slots are 40 minutes, which is usually enough for 3-4 pulls. (Actually more, if you want...)

It's a great social educational event, too, as lots of people come to watch and compare notes. Feel free to stop in and hang out even if you're not dyno-ing.

If you're dyno-ing your car, you'll get a paper graph to take with you, and we can also email you your dyno data files, so you can store/analyze/post your results to your heart's content.

Please call (571) 434-8333 with your credit card in hand to reserve a slot. We'll just keep the card number in case you don't show up. You can pay however you want on the day of.

You did, and we still cannot. But there are lots of ways to deal with this. These days, you can just set a smartphone on video record looking at the dash (you do have a boost gauge, I take it?) and that can be your boost logger...

Looks like there's quite a bit more interest than we have slots, so I'm looking to schedule another dyno night around the end of February. Perhaps some of you Bimmer folks may jump in before it's full...
